Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

OBJECTIVE: To assess the efficacy of Qingda Granule (QDG) in ameliorating hypertension-induced cardiac damage and investigate the underlying mechanisms involved. METHODS: Twenty spontaneously hypertensive rats (SHRs) were used to develope a hypertension-induced cardiac damage model. Another 10 Wistar Kyoto (WKY) rats were used as normotension group. Rats were administrated intragastrically QDG [0.9 g/(kg•d)] or an equivalent volume of pure water for 8 weeks. Blood pressure, histopathological changes, cardiac function, levels of oxidative stress and inflammatory response markers were measured. Furthermore, to gain insights into the potential mechanisms underlying the protective effects of QDG against hypertension-induced cardiac injury, a network pharmacology study was conducted. Predicted results were validated by Western blot, radioimmunoassay immunohistochemistry and quantitative polymerase chain reaction, respectively. RESULTS: The administration of QDG resulted in a significant decrease in blood pressure levels in SHRs (P<0.01). Histological examinations, including hematoxylin-eosin staining and Masson trichrome staining revealed that QDG effectively attenuated hypertension-induced cardiac damage. Furthermore, echocardiography demonstrated that QDG improved hypertension-associated cardiac dysfunction. Enzyme-linked immunosorbent assay and colorimetric method indicated that QDG significantly reduced oxidative stress and inflammatory response levels in both myocardial tissue and serum (P<0.01). CONCLUSIONS Both network pharmacology and experimental investigations confirmed that QDG exerted its beneficial effects in decreasing hypertension-induced cardiac damage by regulating the angiotensin converting enzyme (ACE)/angiotensin II (Ang II)/Ang II receptor type 1 axis and ACE/Ang II/Ang II receptor type 2 axis.

Objective: To explore the clinical application value of neural network technology,and to screen the clinical early warning indicators of severe hand-foot-mouth disease(HFMD) by constructing a back propagation neural network(BPNN) model. Methods: The clinical data of children with HFMD admitted to the Department of Infectious Diseases and Pediatrics of the First Affiliated Hospital of Xinxiang Medical University from January2019 to January 2023 were collected.The data were divided into 70% training samples and 30 % test samples using SPSS Modeler 18.0.The BPNN model and Logistic model were constructed to compare and evaluate the prediction accuracy and screening effect of the model. Results: The clinical data of 589 children were collected and analyzed,including 324 cases in the mild group and 265 cases in the severe group.The prediction accuracy of the test set(n=178) of BP neural network model and Logistic regression model was 82.02% and 84.83%,respectively.The area under the ROC curve(95% CI) was 0.791(0.749-0.834) and 0.625(0.577-0.674),respectively.Among the predictive variables output by the BPNN model,the top five factors that had the greatest impact on the grouping were highest body temperature,duration of fever,glutamyl transpeptidase,aspartate aminotransferase,and globulin.There were 3 of the top 10 overlaps in the importance of the predictive variables output by the two models,which were the highest body temperature,duration of fever and limb shaking. Conclusion The BPNN model and Logistic regression model perform well in screening and verifying the risk factors of severe hand-foot-mouth disease,but the comprehensive prediction performance of BP neural network model is better.The top five influencing factors of severe HFMD screened by the BPNN model are the highest body temperature,duration of fever,glutamyl transpeptidase,aspartate aminotransferase and globulin.

Objective:To compare the efficacies of arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement in the treatment of chronic lateral ankle instability (CLAI) concomitant with fibular tendinitis.Methods:A retrospective cohort analysis was conducted on the clinical data of 31 patients with CLAI concomitant with fibular tendinitis, who were treated in Beijing Tongren Hospital, Capital Medical University between March 2019 and December 2021. The patients included 17 males and 14 females, aged 16-57 years [(32.8±9.6)years]. The anterior drawer test and talar tilt test were positive in all patients preoperatively. Diagnosis was confirmed by physical examination and MRI, and calcaneofibular ligament rupture was excluded. Eleven patients received arthroscopic modified Brostr?m procedure combined with peroneal tendon debridement (modified Brostr?m procedure+tendon debridement group), and 20 underwent pure arthroscopic modified Brostr?m procedure (modified Brostr?m procedure group). The operation time, intraoperative blood loss and length of hospital stay were documented. The visual analogue score (VAS) in peroneal tendon area was assessed before operation and at postoperative 2, 6 and 12 weeks. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and foot and ankle outcome score (FAOS) were assessed before operation and at postoperative 6 and 12 weeks. The anterior drawer test was performed at the last follow-up. The foot and ankle ability measure (FAAM) score was assessed before operation and at the last follow-up. Postoperative wound healing and complications were also observed.Results:All the patients were followed up for 4-19 months [(11.3±3.5)months]. The operation time was (66.0±4.2)minutes in the modified Brostr?m procedure+tendon debridement group, which was significantly longer than (61.5±3.4)minutes in the modified Brostr?m procedure group ( P<0.05). There was no significant difference in intraoperative blood loss or length of hospital stay between the two groups (all P>0.05). Compared with the preoperation, the value of VAS was significantly lowered, and the values of AOFAS ankle-hindfoot score, FAOS and FAAM score were significantly increased at different postoperative timepoints (all P<0.01). No significant differences in the values of VAS, AOFAS ankle-hindfoot score, FAOS or FAAM score were seen between the two groups before operation (all P>0.05). The value of VAS was 3.0(3.0, 4.0) points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 4.0(4.0, 4.0)points in the modified Brostr?m procedure group at 2 weeks postoperatively ( P<0.05). The value of VAS was 2.0(1.0, 3.0)points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 3.0(2.3, 3.0)points in the modified Brostr?m procedure group at 6 weeks postoperatively ( P<0.05). At 12 weeks postoperatively, there was no significant difference in the value of VAS between the two groups ( P>0.05). There were no significant differences in the values of AOFAS ankle-hindfoot score and FAOS between the two groups at 6 or 12 weeks postoperatively (all P>0.05). The anterior drawer test was negative in all patients at the last follow-up. No significant difference was seen in the value of FAAM score between the two groups at the last follow-up ( P>0.05). All incisions were healed well in the first stage after operation, without the occurrence of joint infection, impaired joint motion, nerve injury or deep vein thrombosis. Conclusions:Arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement can both improve the foot function in CLAI patients concomitant with fibular tendinitis. However, the combined treatment allows for early pain relief, without increasing the risk of complications, and can therefore contribute to a faster postoperative recovery.

Objective:To explore the relationship between microsatellite instability (MSI) and Ki-67 expression level and the clinicopathological features of colorectal cancer, and investigate their impact for prognosis, so as to provide reference for prognostic judgment of colorectal cancer.Methods:The data of 183 patients who underwent radical colorectal cancer surgery and were diagnosed pathologically in the Department of General Surgery, the First Affiliated Hospital of Xinxiang Medical University from January 2017 to December 2019 were retrospectively analysed, including 101 males (55.2%)and 82 females(44.8%), ranged from 20 to 86 years and the mean age was(60.27±13.13)years. According to the results of mismatch repair protein immunohistochemical staining, the patients were divided into MSI-H group ( n=32) and MSI-L/MSS group ( n=151). According to the results of Ki-67 antigen immunohistochemical staining, the patients were divided into low Ki-67 expression group (<82.5%, n=136) and high Ki-67 expression group (≥82.5%, n=47) , among which 62 cases (78.5%) with low Ki-67 expression and 17 cases (21.5%) with high Ki-67 expression were in patients with Ⅲ+ Ⅳ stage colorectal cancer. The data of clinicopathological features, disease-free survival, and overall survival were collected and analyzed. The cotegorical variables were presented as n(%), and the comparisons between groups were performed using Chi-square test or Fisher′s exact test. The multivariate Logistic regression model was used to estimate the correlation between microsatellite instability and Ki-67 expression level and clinicopathologic characteristics of colorectal cancer. Kaplan-Meier survival curve and COX proportional hazards regression model were used to analyze the correlation between microsatellite instability and Ki-67 expression level and disease-free survival and overall survival. Results:Single factor analysis showed that the differences in gender ( χ2=4.37, P=0.037), tumor site ( χ2=26.40, P<0.001), tumor maximum diameter ( χ2=11.12, P=0.001) and nerve invasion ( χ2=5.53, P=0.019) between MSI-H group and MSI-L/MSS group were statistically significant. Multivariate Logistic regression model analysis showed that only gender ( OR=3.013, 95% CI: 1.183-7.672, P=0.021), tumor location ( OR=0.167, 95% CI: 0.067-0.419, P<0.001) and nerve invasion ( OR=0.202, 95% CI: 0.042-0.968, P=0.045) were independently correlative factors for MSI status. In Ⅲ+ Ⅳ stage colorectal cancers, the difference in tumor site between low Ki-67 expression group and high Ki-67 expression group was statistically significant( χ2=3.91, P=0.048). Multivariate Cox proportional hazards regression model analysis revealed that high Ki-67 expression ( HR=0.301, 95% CI: 0.118-0.768, P=0.012; HR=0.275, 95% CI: 0.083-0.912, P=0.035) and MSI-H ( HR=0.072, 95% CI: 0.010-0.525, P=0.009; HR=0.122, 95% CI: 0.017-0.900, P=0.039) were independently protective factors for disease-free survival and overall survival. Conclusions:MSI-H colorectal cancer is common in males, right-sided colonic cancers and non-neuroinvasive patients. In stage Ⅲ+ Ⅳ colorectal cancer, the expression level of Ki-67 in right-sided colonic cancer was lower than in left-sided colorectal cancer. Patients with MSI-H and high Ki-67 expressive colorectal cancer had longer disease-free survival, longer overall survival and better prognosis.

Acute Achilles tendon rupture (AATR) is one of the most common sport injuries in clinical practice, which is usually treated surgically or non-surgically. Regardless of treatment choice, early weight bearing should be encouraged to promote tendon healing. After ruptured Achilles tendon is healed, permanent defects in the biomechanical function of the patients′ affected lower limbs are found and performance in running, jumping, and competitive sports is affected, which may be due to a decrease in the flexion strength of the ankle as a result of tendon elongation following the repair of an Achilles tendon. The methods for evaluating tendon elongation can be divided into indirect measurement and direct measurement. Achilles tendon resting angle (ATRA) is the most commonly used and reliable indirect measurement index, while ultrasound and MRI are commonly used for direct measurement. However, there is no recommended "gold standard" at present. Among the potential influencing factors of tendon elongation, the choice of surgical or non-surgical treatment, different tendon suturing methods and start time of weight bearing have attracted attention and are still controversial. The authors reviewed the research progress of tendon elongation's effects on lower limb biomechanics, evaluation of tendon elongation, and factors affecting tendon elongation so as to provide reference for clinical diagnosis and treatment as well as related researches.

Moringa oleifera leaves are known for their "Virechana"(purgative) effect in Ayurvedic medicine in India. This study compared the purgative effects and mechanisms of M. oleifera leaves with the reference Rhei Radix et Rhizoma to establish a foundation for the further application of M. oleifera leaves in traditional Chinese medicine(TCM). Using network pharmacology and molecular docking methods, this study identified the material basis, common targets, and signaling pathways through which Rhei Radix et Rhizoma and M. oleifera leaves exerted their purgative pharmacological effects. A low-fiber diet-induced constipation mouse model was established to measure fecal parameters and small intestinal propulsion rate, and histological changes in the colon were observed using HE staining. Relative expression levels of relevant genes and target proteins were assessed using RT-qPCR and immunohistochemistry, respectively. The results showed that mapping the targets of Rhei Radix et Rhizoma and M. oleifera leaves onto the biological process network of constipation revealed close proximity, indicating that they may exert their therapeutic effects on constipation through similar biological processes. Molecular docking results indicated that compounds such as sennoside C and isoquercitrin could target serine/threonine protein kinases(AKT1) and mitogen-activated protein kinase 3(MAPK3), thereby affecting MAPK and calcium signaling pathways to promote defecation. Animal experiments demonstrated that both M. oleifera leaves and Rhei Radix et Rhizoma increased the number of fecal pellets and water content in constipated mice, improved small intestine motility, colon mucosal thickness, and muscle layer thickness, upregulated the gene expression levels of AKT1 and MAPK3 in the colon, and downregulated the expression of AQP3 protein. These findings suggest that M. oleifera leaves and Rhei Radix et Rhizoma share similarities in their therapeutic efficacy and mechanisms for treating constipation. Using Rhei Radix et Rhizoma as a reference can provide a better understanding of the characteristics of the "Virechana"(purgative) effect of M. oleifera leaves in TCM.
